AI Technical Summary

Problems solved by technology

[0006] The above-mentioned existing technical solutions have the following defects: in the production process of the geomembrane, when the short fibers are loosened and carded, due to the humid environment (especially in coastal areas), the raw materials themselves will be a little wet, resulting in Short fibers will merge together to a certain extent, which is not conducive to loosening and combing

Embodiment 2

[0049] refer to Figure 7 , the difference with Embodiment 1 is that the end cover 2 can be replaced by a bracket 9, the bracket 9 can be cross-shaped, the end of the bracket 9 is supported on the side wall of the cotton opening box, and the stirring motor 3 can be controlled by the bracket 9 Support, and the setting of support 9 makes it easier for water vapor to escape from the cotton opening box.

Embodiment 3

[0051] refer to Figure 8 , a smoke hood 641 is arranged above the film extrusion die 64, and the smoke hood 641 is connected with an exhaust gas purification tower 642, and the smoke generated in the film production process is sucked into the exhaust gas purification tower 642 through the smoke hood 641, and the smoke After purification, it is discharged into the atmosphere.

Embodiment 4

[0053] refer to Figure 9 , A dust collection hood 13 is arranged above the upper hopper 1, and the dust collection hood 13 is communicated with a bag filter 14, and the generated smoke is collected by the bag filter 14. Certainly, also can be provided with dust suction cover 13 and carry out dust removal at cotton opener, cotton feeder and carding machine.

Abstract

The invention relates to a processing technology for a new type of clean plastic composite polymer material, which includes a cotton opener, a cotton feeder, a carding machine, a net laying machine, a needle punching machine, a geotextile winder, a plastic extruder, The calender and the geomembrane winding machine also include an upper hopper connected with the cotton opener, the upper hopper includes a cotton opening box, and a cavity for passing hot water is formed in the cotton opening box. The invention has the effect of fully loosening the short fibers, and at the same time achieves the purpose of clean production. The harmful smoke generated in the film production is collected and purified through the waste gas purification tower and then discharged, which is more environmentally friendly; the short fibers are treated by the bag filter. The dust generated during feeding is collected uniformly, which is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a processing technology of a geomembrane. Background technique [0002] The new clean plastic composite polymer material can also be called geomembrane. The geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the plastic film. Anti-seepage performance. At present, the plastic films used for anti-seepage in related projects at home and abroad mainly include polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified asphalt blend geomembrane) is also designed for tunnel applications. ), HDPE (high-density polyethylene geomembrane) and LDPE (low-density polyethylene geomembrane). They are a kind of polymer chemical flexible material with small specific gravity, strong extensibility, high adapt...
